Is It Coral?

[bountyhunter23]

So i got rock off the internet and there is some kind of white coral growing on it. I wasnt really shooting for coral but it looks cool. OR it could not be coral but it looks like it. Its white with brown spots....ish. So if it is coral but if it is i need to put a 50/50 in or some type of blue lighting in right?

could be coral, could be sponge, could be a funky kelp, (probably sponge though)

maybe it could be bleached out coraline?? one of my snails recently sat at the top on the tank and bleached his coralin to a pure white...now it just looks ugly...
